Difference Between Audio CD And Data CD
By admin
A Compact Disc (CD) is an optical disc used to store digital data. As CDs become popular, now we can easily get CD supplies, including CD labels, cases and racks, at the store level or online. CDs come most commonly in CD-R, CD-RW, CD-ROM and VCD format and can fit 700MB on a disc as a data CD or 80 minutes as an audio CD.The confusing part is how do audio CDs and data CDs differ? Firstly is not the actual media that is different, but the way in which the data is written on the disc. Audio CDs have to be readable by a CD player, so there was a standard made so that all audio CDs would be created in such a way that a player anywhere in the world could understand. This differs from Data CDs where any type of file can be copied to a CD, including word documents, images, music etc. When copying music to a data disc, the music will still be in one of the audio formats you used and hence unreadable by conventional CD players. Popular formats include MP3, WMA, OGG and AAC. Instead of storing a hopping 700MB per album, you can decrease the amount to as low as 50MBs per album without too much reduction in sound quality.
